Rubber foam insulation materials are mainly made from high-performance nitrile rubber and polyvinyl chloride, and are processed through special processes such as mixing, vulcanization, and foaming. Their main characteristics are: Low density, enclosed bubble structure, thermal conductivity, water vapor permeability, low water absorption, rich flexibility, easy construction. It is applicable to a wide temperature range, from -40 ℃ to 105 ℃, and has good aging resistance and durability. The flame retardant effect meets the national B1 level standard. Green and environmentally friendly, fully compliant with national environmental requirements from production to installation, with an overall beautiful appearance. Based on the above characteristics, this product is widely used for insulation and heat preservation of various water and steam pipelines in industries such as central air conditioning refrigeration rooms, buildings, ships, and vehicles, and has achieved ideal results. Due to the softness and resistance to bending and twisting of this material, it can be processed into handles and extensions for fitness equipment, medical devices, and daily necessities.
